Intermediate Registers, Counters & Memory 9 구성 요소
4-Bit Johnson Counter
A twisted-ring counter: the inverted output of the last flip-flop feeds the first, producing eight unique states from four flip-flops.

작동 원리
A ring of four D flip-flops where the INVERTED output of the last flip-flop feeds the first. Starting from 0000 it fills with 1s then empties, giving eight unique states from four flip-flops.
